Author M.R. Carey has shared the first trailer for The Girl With All the Gifts, Warner Bros’ adaptation of his 2014 novel about a very special girl guarded by scientists, soldiers, and a doting teacher in post-apocalyptic Britain. Every morning, Melanie (Sennia Nanua) dutifully straps herself in to a wheelchair to attend class with other children, also restrained, under the tutelage of their beloved Miss Justineau (Gemma Arterton). But beyond the walls of their abandoned army base, infected “hungries” are trying to break in. Within those walls, Dr. Caldwell (Glenn Close) is testing a cure, but she needs a very particular ingredient.

The trailer looks to be a pretty faithful adaptation of Carey’s book, following Melanie, Miss Justineau, Dr. Caldwell, and Sergeant Parks (Paddy Considine) from the base to discovering the truth behind the infection and fighting hungries along the way. The only negative reaction so far seems to be the online backlash regarding the whitewashing of Miss Justineau (who is clearly described as a woman of color in the text).

On the plus side, newcomer Sennia Nanua looks as if she will give a powerful performance as the eponymous girl with all the gifts. Watch the trailer:

The Girl With All the Gifts will be released September 23 in the UK and (according to Carey) around the same time in the US.
